How do you make a water purifier with household items?
Constructing your own DIY water filter not only conveniently provides clean water — it also may save your life in unusual situations that you don’t have pure water. An improvised water filter will improve the taste of and remove harmful contaminants from ground or lake water. The following steps explain how you can put together a charcoal water filter using everyday items.
You will need completely cooled, fresh (preferably) charcoal such as that from a camp fire or grill; a cylindrical container such as a bucket or two-liter soda bottle cut at one end; a large stone; and grass or sand.
To fashion your DIY charcoal water filter, you will need to craft a funnel to act as the filter. For this you can use a large leaf or strip of tree bark. If you are using a soda bottle, cut the top off and flip it upside down so that the bottle cap is pointing toward the bottom of the bottle.
You will need to poke a hole in the bottle cap so that water can be filtered.
Once you have your mechanism ready, use the stone to crush your charcoal then place it into the funnel. Next, pack sand or grass on top of the charcoal as this will aid the filtering process.
Finally, pour the ground or lake water into the funnel.
The water will filter down into the container slowly.
Repeat this process until the water reaches the clarity you desire.
For the most sterile results, boil the water a few minutes after you have filtered it to get rid of any remaining microscopic contaminants.
Is charcoal water healthy?
Activated charcoal is a odorless black powder and it have been used for a long time helping to filter water since it can interact with it. It can absorb toxins, drugs, viruses, bacteria, fungus and some harmful chemicals found in water. The body is unable to absorb charcoal, and so the toxins that bind to the charcoal leave the body in the feces.
In commercial settings, such as waste-management centers, operators often use activated carbon granules for one part of the filtration process. Dozens of water filtration products are also designed for at-home use, using carbon cartridges to purify water of toxins and impurities.
A 2015 study found that water filtration systems that used carbon removed as much as 100 percent of the fluoride in 32 unfiltered water samples after 6 months of installation.
Activated charcoal is produced by superheating natural sources of carbon-rich materials, such as wood, peat, coconut shells, or sawdust, to very high temperatures. The ‘activation’ process strips the charcoal of previously absorbed molecules and frees up bonding sites again. This process also reduces the size of the pores in the charcoal and makes more holes in each molecule, therefore, increasing its overall surface area.
The manufacture of activated charcoal makes it extremely adsorbent, allowing it to bind to molecules, ions, or atoms. Concluding, charcoal water it’s very healthy because it had the most of contaminants took off.
How does gravel sand and charcoal filter water?
First, the gravel layer catches large pieces of debris, such as twigs, leaves, and bugs.
Next, the sand layer catches smaller particles, such as dirt and grit, and makes the water look clean.
Finally, the charcoal layer gets rid of bacteria and some chemicals.
But if you don’t have Charcoal, can you still make a Water Filter? Yes!
How do you make a homemade water filter without charcoal?
To make a water filter without activated charcoal, you need a replacement material that has pores large enough to allow water to pass through, but small enough to catch sediment, pathogens, or other impurities. Sand or ceramic are the best materials to use as replacements for activated charcoal.
Can you make sand water filter?
Put it upside down in the beaker.
Pour the pebbles into the bottle.
Then pour the coarse sand on top of the pebbles and the fine sand on top of the coarse sand.
Carefully pour about two liters of clean tap water through, being careful not to disturb the top layer of sand.
A tasteless and odorless liquid at room temperature, it has the important ability to dissolve many other substances, the versatility of water as a solvent is essential to live organisms.
Life is believed to have originated in the aqueous solutions of the world’s oceans, and living organisms depend on aqueous solutions, such as blood and digestive juices, for biological processes.
It is one of the most plentiful and essential of compounds, it is vital for all known forms of life, even though it provides no calories or organic nutrients, we are 80% made of water.
Unfortunately, in our modern society, not every water that comes to us is clean, even though it appears clean, tap water for instance has various contaminants that can harm your health, such as chlorine, microorganisms, flour, lead, etc. If you want to know more you can have a look at your contaminants page right here.
So, answering your question: The best way to filter tap or any other water is to buy the most useful tool against these chemicals and contaminants, which is a Water Filter.
We know that sometimes we cannot afford to buy such equipment, because we are having economical problems, or even we are in places that don’t have it for sale, or maybe you are going on vacation or camping and need fresh and clean water, these are common situations.
You must be asking yourself what are the problems of ingesting unpure water in those cases we mentioned before, I mean, It’s just a few times, right?
And this is the crucial point where you do not want to think like that!! Drinking impure water is the first cause of death for people that are lost in the woods or camping, etc.
You can get very sick and spoil your trip or even worse! Thinking about people that can’t afford the water filter we are going to share How To Make Your WaterFilter- DIY
What is the simplest way to purify water?
The simplest and most reliable method to purify water is to boil it for a good amount of time.
High temperatures cause the bacteria and virus to dissipate, removing all impurities from the water.
In doing so, chemical additions cease to exist in the water as well.
However, boiling uses fuel and could take a while. Furthermore, you will need to filter the water to remove all solid particles especially if the water was taken from a doubtful water source.
Use of Iodine solution, tablets or crystals
This is an effective and more convenient method, It can kill viruses and bacteria.
Once you drop the tablet into the water container
Shake the container and hold the bottle upside down
Have the lid slightly unscrewed to let the iodine to flow into the threads of the bottle cap.But It takes about thirty minutes before you can drink the treated water, it has an unusual aftertaste. Be careful: It is also not suitable for pregnant women.
A quick trick to make it look better is to pour the water through a coffee filter or clean cloth.
This won’t make it safe to drink, but it can improve the clarity of the water, which will help the following disinfection methods work better.
And remember, if you are very sensitive to chemicals, you can always just boil your water for 10 minutes instead of chemically treating it.
Our next trick is to carefully use ordinary household bleach to disinfect water.
As a rule, colder water needs a little more bleach than warm water, and muddier water needs more bleach than clear water. Let the water stand for several minutes if it is muddy, and just pour the clearer water off the top. This will make disinfection much more effective.
Add 2 to 4 drops of ordinary chlorine bleach per quart of water.
Use 2 drops if the water is warm and clear.
Go to 4 drops if it is very cold or murky – or both.
Put the bottle lid back on, and shake the container for a minute.
Then turn the bottle upside down, and unscrew the cap a turn, or two.
Let a small amount of water flow out to clean the bottle threads and cap.
Screw the lid back on tight, and wipe the exterior of the bottle to get the chlorine on all surfaces.
Use a clear PET bottle (the one typically used for sodas and soft drinks) as some glasses block out too much of the UV-A rays – If the water is too cloudy then filter it first using a clean cloth before pouring it into the bottle.
Lay the bottle face down under the sun, If it’s a clear sky or not too cloudy – then just 6 hours of sunlight is enough. If not, 2 days of exposure might be required.
Boiling water can kill almost all bacteria and viruses, to speed up the process you can cover the pot and let it boil.
Chlorine kills the bacteria in the water but can be harmful if added in excess. The package will usually tell you how many drops for how many liters and for how long you need to wait. It typically takes about 30 minutes to treat the water.
Here is how to make a cheap Water Filter in 12 Steps:
Plastic bottle or comparable food-safe container
Another container for clean water
Clean cotton or cheesecloth
Coffee filter or porous cloth
Sand (fine and coarse)
Gravel or pebbles
Step 1 – Cut Bottom Off
Use scissors or a knife to cut off the bottom part of the bottle you will be putting the filter material in.
Step 2 – Cut Drain Hole
Use scissors or a knife to poke a small hole in the cap. If there is no cap, cut off the top of the bottle instead of the bottom for the previous step then poke several small holes in the bottom of the bottle.
Step 3 – 1st Layer: Straining Fabric
Stuff the bottom of the bottle with a fine cloth or paper fabric, such as a coffee filter, cheesecloth or cotton stuffing.
Sand and grass can also be used in this first stage. Fill the bottom with about 3 inches of grass clippings to filter out larger particulates and help give water a clean taste from chlorophyll contained in the grass. Then fill with 3-4 inches of very fine sand.
Be careful not to use poisonous or unidentified weeds when collecting grass clippings. Do not use Highway Department sand, as it can be full of road salt and chemicals.
Step 4 – Break Up Charcoal
Take charcoal from campfire or BBQ charcoal (do not use match/instant light type because it’s soaked in chemicals) and use hammer or rock to break it down into the smallest particles you can.
Step 5 – Layer 2: Pulverized Charcoal
Pour about 3 inches of pulverized charcoal into a bottle. If available, cover with another coffee filter to prevent the charcoal from being displaced too much during filtering.
Step 6 – 3rd Layer: Fine Sand
Add a 2-3 inch layer of the finest sand you can find. This and the subsequent layers you will add are to filter out particulates in the water.
Do not use Highway Department sand, as it can be full of road salt and chemicals.
Step 7 – 4th Layer: Coarse Sand
Add a 2-3 inch layer of coarse sand or very small pebbles.
Step 8 – 5th Layer: Fine Sand
Add 2-3 inch layer of the fine sand. Multiple varying filter stages (like a reverse osmosis system) ensures that most of the particles present in the water are caught.
Step 9 – 6th Layer: Gravel
Add a 2-3 inch layer of gravel or small rocks to prevent the water from being poured in from displacing the sand.
Step 10 – Top Strainer
Cover top of the filter with a piece of porous cloth, such as a bandana or cheesecloth. This step is optional but helpful in straining any large debris from the water and stop the pouring from displacing the sand inside the filter.
Step 11 – Pouring & Collecting
Pour water slowly into the filter while holding it over the second container.
Make sure to wipe off or clean the collection container. Pour water slowly so as not to disturb filter layers too much or to cause filter container to overflow and possibly spilling unfiltered water into the collection container.
Step 12 – Sterilize Water
Even though you have filtered the water through many different layers, microbes can still exist in the water and it still needs to be sterilized. Boiling the water in a pot or kettle is the easiest way.
You can also use sunlight to sterilize water. Pour filtered water into a clean, clear plastic or glass bottle up to 3/4 full and screw-on cap. Shake for thirty seconds to add more oxygen to the water. Place on a light or reflective surface in direct sunlight. The amount of exposure it needs it dependant on weather conditions. A clear day requires 6 hours of exposure whereas 50% or more cloud coverage will require 2 days of sunlight.
